Application filed February 14, 1913.

To all whom it may concern: 7

Be it known that I, HENRY F. LAMB, a citizen of the United States,residing at Bellingham, in the county of VVha-tcom and State ofWashington, have invented new and useful Improvements in Separators, ofwhich the following is a specification.

My invention relates in general to separators and has particularreference to that class of devices peculiarly adapted to separating sandfrom gravel or extracting the finer elements from the coarser ones inany similar substance.

The principal object of my invention resides in the provision of meanswhereby the separated elements may be individually conveyed to vats,containers or similar structures.

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawingsdescribed in the following specification and then more particularlypointed out in the claim which is appended hereto and forms a part ofthis application.

With reference to the drawings throughout which similar referencenumerals designate corresponding parts: Figure 1 is a front elevationwith portions of the box broken away to more clearly disclose theassembled relation of the various parts. Fig. 2 is an end elevation.Fig. 3 is a section on the line 33 of Fig. 1.

Proceeding now to the description of the drawings my invention includesthe separator box designated as an entirety by the numeral 1, theconveyer chute 2, the outlet pipes 3 and 4, the worm 5, the screen 6 andthe agitating cams 7.

The box 1 is constructed according to the common practice and may beangularly supported by any suitable means. Hingedly mounted at the upperend of the box is the worm housing 8, on the upper portion of which theconveyer chute 2 is seated. The housing 8 is provided with the hingeddoor 9 whereby access may be had to the worm 5 in the event that themechanism becomes clogged by the gravel. A door 10 is also carried bythe housing 8 providing access to the interior of the box 1. Spaced fromthe lower end of the box and held in rigid relation thereto is thedivision wall 11 which may be suitably braced by the members 12. Thepipe 3 communicates with the chamber Specification of Letters Patent.

formed by the spacing of the wall 11 from the lower end of the box and apipe 4 is in communication with the upper chamber of the box.

The worm 5 is rotatably mounted within the housing 8 and is disposed toevenly distribute the incoming gravel along the upper portion of thescreen 6. The baffle shelf 13 is secured to the wall of the housing bythe brace 14 and co-acts with the worm!) in the distribution of thegravel. The screen 6 which is of the common type and is provided topermit the finer portions of the gravel to sift through into the uppercompartment of the box, is secured at its lower end to the upper edge ofthe partition wall 11 and is pivotally connected at its upper end withthe shaft 15 through the medium of the connection 16. The screen 6carries on its under side the longitudinally extending series of plates17, 18 and 19. Secured to the plates 17 and 19 are a plurality ofhelical springs, the lower ends of which are fixed to the rod supportingplates 20. The plates 20 carry the stop rods 21 which are mounted withinthe spring and are adapted to engage the members 17 and 19 when thescreen is forced toward the wall of the box by the weight of the gravel.

In order to thoroughly separate the sand from the gravel, it isdesirable that the screen be continuously agitated and to accomplishthis result I employ the cams 7. These members are keyed to therotatable shaft 22 and are disposed for engagement in their rotationwith the plates 18. The cam consists of a circular disk 23, having aplurality of strap members 24 secured thereto.

The above disclosures clearly explain the construction of my inventionand 1 now pass toa brief explanation of the operation of the separator.

The gravel is introduced into the box through the chute 2 and falls uponthe worm and shelf at the adjacent end thereof. The gravel isdistributed by the Worm evenly along the upper portion of the screen andthen passes by the force of gravity along the inclined surface of thesaid screen. It will be seen however, that if the shaft 22 is connectedto the same means employed for rotating the worm, the screen will begiven continuous agitations by the action of the strap 24. against theplates 19. The effect of this agitation will of course be increased bythe springs 20. As a result of the agitation of the screen, the finerelements of the gravel Will fall into the upper chamber of the box andwill pass out through the pipe 4 While the coarser elements Willcontinue along the screen and drop into the loWer compartment of the boxsubsequently passing out through the pipe 3 whence they may be conductedto any suitable container. In this connection it Will be understood thatWhile I have described my invention as being peculiarly adaptable forthe separation of'sand and gravel, it may be also employed in separatingthe coarse and fine elements of any substance; and that While I havedescribed the pipes 3 and 4 as leading to containers, it

Will be seen that the box may be readily mounted in such manner as topermit the sand and gravel to fall Wagon.

It Will be further understood that various minor changes in details ofconstruction and arrangement of parts may be made Within the scope ofthe appended claim and Withdirectly i'nto a out sacrificing any of theadvantages of this invention.

What is claimed is:

'. A separator comprising an inclined housing having an opening in theupper end thereof, a vertical housing hingedly con nected to theinclined housing and covering the opening therein, a conveyer leadinginto the top of the vertical housing, a conveyer screw rotatably mountedWithin the vertical housingibeloW the conveyer, a rod extending theinclined housing near the loWer end thereof, cams carried by saidtransverse shaft and adapted to engage the contact the screen, a shaftextending transversely of plates on the screen, a partition secured inthe vertical housing adjacent the lower end of the screen, and outletchutes leading from said inclined housing at each side of the partition.
